Construct the following quadrilateral:
Quadrilateral PLAN
PL = 4 cm
LA = 6.5 cm
∠P = 90°
∠A = 110°
∠N = 85°
Steps of construction:I. Draw a line segment AL = 6.5 cm.
II. At A, draw
such that
III. At L, draw
such that
Note:
is not given, but we can determine it using angle sum property
Sum of the three given angles =
∴ The fourth angle
IV. From
, cut-off LP = 4 cm.
V. At P, draw
such that
Let
and
intersect at N.
Thus, PLAN is the required quadrilateral.
